Leonardo AI: Advanced editing with Canvas Editor

Demo summary

The tutorial walks through using the Canvas Editor to perform inpainting with masks, outpainting to extend image borders, and merging two images together.

Step-by-step

  1. Open the Canvas Editor from the left menu
  2. Click Upload Image to add files from your computer or generation list
  3. Enable the Select tool to move, scale, or rotate images
  4. Position the generation frame over the region you want to edit
  5. Use the Draw Mask tool to specify the exact area for AI modification
  6. Enter a prompt at the bottom and click Generate
  7. Select your preferred variation from the results

Options

  • Drop multiple images onto the canvas simultaneously
  • Use the Sketch tool to brush on the canvas
  • Use the Text tool to add text elements
  • Switch to the Erase tool if the Mask tool is not working well
  • Extend image borders by placing the generation frame outside the current image
  • Merge two images by erasing a subject's background and moving it onto another image

Watch out for

  • The AI can only analyze and work within the region delimited by the colored generation frame

Tips

  • Hold CTRL/CMD and use the mouse wheel to zoom
  • Hold the Spacebar to pan around the canvas
  • Use the Draw Mask tool to preserve specific subjects while changing backgrounds or details like hair color
  • When merging images, drop a mask where the two images meet and use prompt guidance to blend them

Highlights

making it easier to focus on different areas of the image
